* DEVICE FOR PREVENTING LADDERS FROM SLIPPING.

Specification of Letters Patent. Patented IMar. 24, 1914.

Application filed October 30, 1913. Serial No. 798,292.

To all whom it may concern Be it known that I, VICTOR TAKAOH, citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements inDevices for Preventing Ladders from Slipping, of which the following isa specification.

This invention is a device for preventing ladders slipping. It isattached to the foot of the ladder leg or stile and engages the groundin order to give the ladder a secure footing when it stands in anupright position. Either one or both legs of the ladder may be providedwith the device and it is particularly serviceable when the foot of theladder stands on hard ground or a solid or slippery surface.

The invention is illustrated in the accompanying drawing in which Figurel is a side elevation of the lower end of a ladder provided with thedevice. Fig. 2 is a rear view of one leg, with the de vice in placethereon.

Referring specifically to the drawings 6 indicates the leg or stile ofthe ladder, and 7 is a metal plate which is fixed thereto on the rearside, slightly above the lower end thereof. This plate has a pair ofears 8 projecting rearwardly, and between these is pivoted, at 10, acatch lever 11, which at its lower end is sharpened and formed withclaws or teeth 12 adapted to engage the ground or surface on which theladder stands. The upper end 13 of the lever projects above the ears inposition to stop against the plate 7, when the ladder is suiticientlyinclined, and another stop, 14, is also formed on the lever below thepivot, and this serves to hold the catch or claw end of the lever out inposition to engage the ground whenever the ladder is stood up.

In the use of the device, when the ladder is set up against a buildingor the like the teeth 12 will engage the ground, with the upper end 13of the lever against the plate 7, and such engagement of the teeth willprevent any slipping movement of the foot of the ladder. The pivotalconnection of the latch lever also enables the ladder to be pushed up orstraightened, by permitting the lever to swing and disengage its clawfrom the ground or surface, and a further object of said pivotalconnection is, that it permits a desired amount of movement when theladder happens to be standing upon an uneven surface or ground therebypreventing the foot of the ladder from slipping. Also when it is desiredto resharpen the claw of the lever the latter can be readily removed andreplaced.

What I claim as new is:

1. A. device for slipping, comprising a plate adapted to be attached tothe rear side of the ladder leg, and a catch lever pivoted to the plate,with its lower end adapted to engage the surface on which the ladderstands, and its upper end adapted to stop against the plate.

2. A device for preventing ladders from slipping, comprising a plateadapted to be attached to the rear side of the ladder leg, and a catchlever pivoted to the plate, with its lower end adapted to engage thesurface on which the ladder stands, and its upper end adapted .to stopagainst the plate, the lever having a projection below the pivot,adapted to stop against said plate and hold the lower end of the leverat a distance from the ladder leg, in position to engage the surface onwhich the ladder stands.

3. A ladder the leg of which is provided at its lower end and on itsrear side with an upright catch lever pivoted thereto, the lower end ofwhich engages the ground adjacent the foot of the leg and the upper endof whichextends above the pivot in position to stop against the leg whenthe lower end is so engaged.

In testimony whereof, I do affix my signature in presence of twowitnesses.
